濮城油田卫42、卫43断块属于典型的低孔、低渗、非均质油藏,采取常规开发方案无法对其进行经济有效的开采。通过油藏地质特征、开发历程及现状分析,区块油井普遍存在"四低"现象(产能低、液面低、含水低、采出程度低)。从油藏压裂改造工艺研究出发,对于低渗油藏,压裂改造油层是改善渗流能力,提高油层产量的主要方式。本文通过对卫42、卫43断块油藏的压裂改造工艺研究与实施,区块油水井取得了良好的开发效果,油藏开发指标得到明显改善。
濮城油田衛42、衛43斷塊屬于典型的低孔、低滲、非均質油藏,採取常規開髮方案無法對其進行經濟有效的開採。通過油藏地質特徵、開髮歷程及現狀分析,區塊油井普遍存在"四低"現象(產能低、液麵低、含水低、採齣程度低)。從油藏壓裂改造工藝研究齣髮,對于低滲油藏,壓裂改造油層是改善滲流能力,提高油層產量的主要方式。本文通過對衛42、衛43斷塊油藏的壓裂改造工藝研究與實施,區塊油水井取得瞭良好的開髮效果,油藏開髮指標得到明顯改善。
복성유전위42、위43단괴속우전형적저공、저삼、비균질유장,채취상규개발방안무법대기진행경제유효적개채。통과유장지질특정、개발역정급현상분석,구괴유정보편존재"사저"현상(산능저、액면저、함수저、채출정도저)。종유장압렬개조공예연구출발,대우저삼유장,압렬개조유층시개선삼류능력,제고유층산량적주요방식。본문통과대위42、위43단괴유장적압렬개조공예연구여실시,구괴유수정취득료량호적개발효과,유장개발지표득도명현개선。
Pucheng Oilfield W 42,W43 block is typical of low porosity,low permeability,heterogeneous reservoir,in the conventional development plan can not be cost-effective mining.Through the reservoir geological characteristics,development history and status quo analysis,the prevalence of oil blocks,"four low" phenomenon(low productivity,low surface,low water content,taken out of the low level).Research from the reservoir fracturing process starting,for low permeability reservoir,fracturing the reservoir is to improve the flow capacity,enhance oil production in a major way.Based on the W42,W43 fault block oil reservoir fracturing process research and implementation,block oil development wells and achieved good results,reservoir development indicators improved significantly.
