【摘要】：低滲透油藏儲量豐富,天然物性差,開發(fā)難度大,開采程度低。合理的井網(wǎng)形式及井網(wǎng)參數(shù)可有效改善低滲透油藏的開發(fā)效果。合理的開發(fā)井網(wǎng)研究一直是油田開發(fā)方案中非常關(guān)鍵的課題,它是確保油田持續(xù)進(jìn)行生產(chǎn)和油田企業(yè)實現(xiàn)經(jīng)濟效益的重要技術(shù)。開發(fā)井網(wǎng)系統(tǒng)是復(fù)雜動態(tài)的油田開發(fā)系統(tǒng)的子系統(tǒng),它由各個單井共同組成。目前低滲透油田開發(fā)井網(wǎng)系統(tǒng)優(yōu)化遇到需要折中考慮的問題：從油田的地質(zhì)特點和開發(fā)經(jīng)濟效益出發(fā),人們普遍認(rèn)為只有采用較小的井距和較大的井網(wǎng)密度,才能達(dá)到理想的開發(fā)效果,可這樣會導(dǎo)致鉆井?dāng)?shù)增加、投入成本提。因此,研究井網(wǎng)的適應(yīng)性,選擇合理的井網(wǎng)形式及井網(wǎng)參數(shù),成為經(jīng)濟有效開發(fā)低滲透油藏的關(guān)鍵問題之一。本文以靖安油田虎狼峁區(qū)長6開發(fā)研究區(qū)為研究對象應(yīng)用實驗室實驗數(shù)據(jù)及錄井、測井等資料了解清楚長6油藏的構(gòu)造特征、儲層特征、流體特征、油藏類型及原始驅(qū)動壓力類型等；在了解該地區(qū)地質(zhì)和流體特征的基礎(chǔ)上,以井區(qū)發(fā)展歷程為參考對油田開發(fā)特征、油藏注水開發(fā)效果加以評價；以上兩部分內(nèi)容為依據(jù),從開發(fā)方式和井網(wǎng)部署兩方面入手進(jìn)行針對長6井區(qū)的井網(wǎng)改造前后不同形式井網(wǎng)、井網(wǎng)密度以及井距合理性的研究。
[Abstract]:Low permeability reservoirs are rich in reserves, poor in physical properties, difficult in development and low in degree of exploitation. Reasonable well pattern and well pattern parameters can effectively improve the development effect of low permeability reservoir. Reasonable well pattern research has always been a key issue in oilfield development scheme. It is an important technology to ensure the continuous production of oil field and the realization of economic benefits of oil field enterprises. Development well pattern system is a subsystem of complex dynamic oilfield development system, which is composed of each single well. At present, the optimization of development well pattern in low permeability oil field meets some problems that need to be considered in the middle. According to the geological characteristics of oil field and the economic benefit of development, it is generally believed that only small well spacing and larger well pattern density can be adopted. In order to achieve the ideal development effect, it can lead to the increase of drilling number and the increase of input cost. Therefore, to study the adaptability of well pattern and select reasonable well pattern form and well pattern parameters is one of the key problems in economic and effective development of low permeability reservoirs. In this paper, taking the development and research area of Hulangmao-Chang 6 in Jingan Oilfield as the research object, using laboratory experimental data and logging and logging data to understand clearly the structural characteristics, reservoir characteristics and fluid characteristics of Chang 6 reservoir. Reservoir type and original driving pressure type, on the basis of understanding the geological and fluid characteristics of the area, taking the development history of the well area as a reference to evaluate the oil field development characteristics, reservoir water injection development effect, the above two parts as the basis, From two aspects of development mode and well pattern arrangement, this paper studies the rationality of well pattern, well density and well spacing in Chang6 well area before and after well pattern reformation.
