The average daily production of more than 80 cubic meters, known as "Blue Gold" of natural gas has been the pride of Xinglongtai oil production plant of Liaohe Oilfield, it is not only a new growth point of economic benefits for the factory, Liaohe Oilfield contributed 70% of the supply of gas products.

在以稠油為主的遼河油田，興隆臺采油廠具有豐富的天然氣資源和開發優勢。近年來，這個廠通過大力提升天然氣經濟產量的貢獻率，為遼河油田增添效益砝碼。去年，該廠累計完成外供天然氣量2.58億立方米，超產1730萬立方米。

In the Liaohe Oilfield, Xinglongtai oil production plant has abundant natural gas resources and development advantages. In recent years, this plant by vigorously promoting the contribution rate of natural gas production, to increase the effectiveness of the Liaohe Oilfield weight. Last year, the plant accumulated for natural gas 258 million cubic meters, 17 million 300 thousand cubic meters of production.

有優勢亦有阻礙

There are advantages and obstacles

3月21日，興隆臺采油廠榆樹臺油田停產氣井臺34-28井采取補層合采措施后，保持日產1.1萬立方米的自噴工業氣流，措施后平穩生產26天，累計增氣25.7萬立方米。同一天，采油作業一區于六站站長李巖打開長停井套管氣回收閥門，確保天然氣“顆粒歸倉”。前者是措施增氣，后者是管理節氣，兩項措施相得益彰。

In March 21st, Xinglongtai oil production plant oil production wells yushutai Taiwan 34-28 wells take up layer commingled production measures, maintain Nissan 11 thousand cubic meters of industrial gas flowing, measures of stable production for 26 days, the cumulative increase of 257 thousand cubic meters of gas. On the same day, oil production operations in the six District of the station Li Yan opened a long stop casing gas recovery valve to ensure that the natural gas particles into the warehouse". The former is a measure to increase gas, which is the management of solar terms, the two measures complement each other.

“興采廠以生產稀油為主，油井不產天然氣是不可想象的，僅這項優勢你們采油廠就能獲得更好的效益產出?！币晃皇图夹g專家在授課時對該廠天然氣開發優勢這樣評價道。

"Xing mining plant in the production of thin oil based, oil wells are not natural gas can not be imagined, only the advantage of your oil production plant will be able to get a better output." An oil technology expert in the teaching of the advantages of the development of the natural gas plant evaluation.

興采廠稀油井生產通常帶有伴生氣，盡管這些油井溶解氣產量高低不定，但開采成本遠低于稠油井生產。據了解，目前該廠氣層氣、溶解氣可采儲量采出程度高達90%和88%，但2015年無新增天然氣儲量，剩余氣層在各油田平面分布零散，難以實施整體新井部署，并且主力氣層連同系數高達60%，連續多年超負荷措施挖潛，各油氣田對天然氣的大規模高速開發已經到了衰竭階段，層間接替潛力越來越小。

Singtex dilute oil production factory usually with gas, although the oil dissolved gas yield is not fixed, but far less than the cost of mining heavy oil production. It is understood that the current plant gas, dissolved gas can be taken out of a high degree of up to 90% and 88% of recoverable reserves, but in 2015 no new natural gas reserves, residual gas in the oil distribution is scattered, difficult to implement the overall deployment of Nii, and together with the main gas coefficient as high as 60%, for many years the overload measures to tap the potential of each oil and gas to gas mass rapid development has reached a stage of failure, more and more small interlayer replacement potential.

控遞減也要重增量

Control the decline should be increased

由于油品品質好、開發成本較低，興古潛山一度被譽為“興采聚寶盆”，然而這塊“寶地”的產氣量近年來快速下降，興古潛山由高峰時的日產氣66萬立方米降低至目前的36萬立方米。

Because of good quality oil, lower development costs, and ancient Qianshan, once known as "singtex cornucopia", but this "treasure house" of the gas production in recent years the rapid decline, from a peak of Xing ancient Qianshan Nissan 660 thousand cubic meters of gas is reduced to the current 360 thousand cubic meters.

為實現潛山油藏增能保壓，該廠制定注氣方案，開展前期非烴類氣驅實驗，有效減緩了潛山油藏遞減的速度。去年，興氣19井和興283井調層后均獲得日產氣超過2萬立方米的高產氣流，成為興采地質措施“開源”的經典案例。2017年，該廠加快了興古潛山天然氣氣驅前期準備工作，預計10月份進入現場實施，標志著潛山增能補壓技術進入新階段。

In order to realize the energy conservation and pressure maintaining of Qianshan reservoir, the gas injection scheme was developed and the non hydrocarbon gas flooding experiment was carried out in the early stage, which effectively slowed down the rate of decline of Qianshan reservoir. Last year, Xing Qi 19 wells and Xing well after the transfer of the layers were obtained more than 20 thousand cubic meters of gas production of high gas flow, Xing Xing geological measures to open source, the classic case of "". 2017, the plant to speed up the ancient Qianshan gas and gas drive preparatory work, is expected to enter the site in October, marking the Qianshan increase energy pressure technology into a new stage.

同時，該廠努力在老區上做天然氣的“加法”。興采廠地質技術人員一方面通過對構造、油氣水分布的重新認識，細化單砂體多層次對比，尋找微構造高點，強化“四性”關系分析，篩選優化高效氣井措施。另一方面，通過加強井震結合落實潛力區域的微構造高點，部署高氣油比井側鉆減緩天然氣產量遞減趨勢。

At the same time, the factory efforts to do in the old area of natural gas addition". Singtex factory technical personnel on the one hand, the geological structure, oil and gas and water distribution of the new understanding, refinement of the single sand body multi-level comparison, find the top of micro structure analysis, strengthening the "four" relationship, optimization and screening of efficient wells measures. On the other hand, by strengthening the combination of well seismic and micro structure of the potential area, the deployment of high gas to oil ratio drilling to slow down the decline trend of natural gas production.

榮興屯油田是開發多年的老區塊，實施側鉆成為近幾年挖潛天然氣的主要手段。榮201-19C井措施前低壓低產，在測井指標進行對比分析、綜合研究后，擬定待射孔層位經過調層后開井，使用3毫米油嘴自噴生產，日產氣1.2萬立方米。

Rongxingtun oilfield is the old block development for many years, the implementation of lateral drilling in recent years has become the main means of tapping the potential of natural gas. Rong 201-19C wells in low pressure and low production measures, logging index comparative analysis and comprehensive research, to be adjusted after the perforation layer layer wells, using a 3 mm nozzle flowing production, Nissan 12 thousand cubic meters of gas.

截至目前，該廠高氣油比油井部署投產11口，初期日增氣7萬立方米；高氣油比措施22口，初期日增氣24萬立方米；共實施側鉆井16口，日增氣1.5萬立方米，階段累計增產天然氣185萬立方米。

As of now, the plant of high gas oil ratio well deployment of production 11, the initial increase of 70 thousand cubic meters of gas; high gas oil ratio measures 22, the initial increase of 240 thousand cubic meters of gas; the implementation of lateral drilling 16, daily 15 thousand cubic meters of gas, the cumulative increase of 1 million 850 thousand cubic meters of natural gas phase.

講策略也講方法

Speaking strategies and methods

“熱爐耗氣量占全廠天然氣消耗的三分之二，針對春季轉暖的實際，去年從4月份開始，在不到一個月的時間里，共實施油井停爐冷輸180臺，累計節氣580萬立方米。對153臺爐子實施控溫輸油，每天可節氣700立方米?！迸d采廠生產運行處一位負責人介紹說。

The "hot stove gas consumption of the total natural gas consumption of 2/3, according to the actual spring warming, from the beginning of April last year, in less than a month's time, the implementation of the wells stop furnace cold transport 180, a total of 5 million 800 thousand cubic meters of solar term. 153 furnace temperature control oil, solar energy can be 700 cubic meters per day." Xing mining plant production and operation of a person in charge said.

節約從日常工作中的點滴小事做起，在“細枝末節”中挖掘效益。該廠基層單位通過采取控制水套爐溫度、安裝節能爐、加熱爐維護等多項節氣挖潛措施，日節約自耗氣約2.9萬立方米；每月各中心站利用高壓水龍管帶，收集長停井天然氣在3萬立方米以上；80%以上采油自然站安裝采暖閥，值班室溫度不超過18攝氏度，循環泵房、配電間等房間控制在10攝氏度以下……

Savings from the daily work of the little things to start, in the minutiae of mining benefits. The factory units by taking control of water jacket furnace temperature, the installation of energy-saving furnace, heating furnace maintenance and other measures on saving solar term, the gas consumption of about 29 thousand cubic meters; by using the high pressure hose with monthly center station, collect long stop wells natural gas 30 thousand cubic meters; more than 80% natural oil production station installed heating valve, on duty room temperature not exceeding 18 degrees Celsius, circulation pump room, power distribution room and other rooms at 10 degrees celsius......

在抓好油井生產挖潛的同時，這個廠積極尋找日常管理中的節氣新路徑，通過改造和設計在增氣創效過程中發揮了四兩撥千斤的作用。

At the same time do a good job in tapping the potential of oil production, the factory actively looking for a new path in the daily management of the solar cycle, through the transformation and design in the process of increasing gas efficiency played a role in the 42 dial.

該廠采油作業一區優化油井控制套壓方法，既不影響原油進系統生產，又能兼顧控套整體效果，目前該種方法適用于全廠56口單井，平均每口單井日均可回收天然氣2.5萬立方米；采油作業五區在推行“自耗氣系統回收套管氣流程”以來，在作業區內19口油井采取該方法，實現日均回收套管氣4500立方米，年累計收套管氣85萬立方米。

The factory production operation area to optimize well casing pressure control method, which does not affect the production of crude oil into the system, but also consider the overall effect of the control set, the method is applicable to all the 56 wells, the average single well day can be recycled 25 thousand cubic meters of natural gas; oil production areas in the implementation of the "gas consumption system the recovery process of casing gas" has been in operation in the region 19 wells adopt this method, realize the daily recovery of casing gas 4500 cubic meters, annual accumulated close to 850 thousand cubic meters of gas pipe.
