摘要
通过对新立油田扶杨油层非主力层泥质粉砂岩层岩性、物性等的研究,揭示了泥质粉砂岩层分布特点及其与有效储层间的相互关系、潜力规模和可利用条件。利用水力压裂与细分层注水等工艺手段,完善了单砂体注采关系,达到增加可采储量、改善开发效果的目的。通过现场实践,实现了165口油井泥质粉砂岩层的有效动用,取得年增油4.22×104t/a的效果,证明有效动用泥质粉砂岩改善油田开发效果的方法是可行的,具有广泛的适用性和推广性。
Through the research on lithology and property of muddy siltstone in Fuyang Oil Layer,Xinli Oilfield,the distribution features of muddy siltstone layer,its relations with effective reservoir,potential scale and available conditions have been revealed.Some techniques such as hydraulic fracturing and water injection into sub-layers are used to improve the injection/production relations of single sand body to reach the goals of increasing recoverable reserves and improving development effect. Through field practice,the effective producing of muddy siltstone layer by 165 producers has been achieved,resulting in annual increase of oil production of 4. 22 × 104 t/a,which proves the improvement of oilfield development effect by muddy siltstone is feasible. The approach can be applied extensively in many fields.
