East Of Sulige Optimizing Design Of Horizontal Wells Fracturing

Along with the drilling technology advancing and drilling cost lowering, horizontal welltechnology has been more widely used and applied to more reservoir types,especially in lowpermeability reservoirs, thus conducive to the development mode transformation ofmultiple-well low-production.Low-permeability oil and gas resources are quite rich all overthe world,thus how to fastly,effectively and economically exploit them has become animportant topic.Horizontal well fracturing changed the near wellbore zone fluid seepage,increased oil production and recovery,which has become an important means of lowpermeability reservoir development.Horizontal well staged fracturing is faced with manyproblems, including: the distribution of well spacing, hydraulic fracturing crack andmorphology, muti-crack design, horizontal well staged fracturing implementation, fractureassessment.we need to start researching on reservoir engineering, in situ stress field,horizontal section of horizontal well staged fracturing design optimization, fracturingtechnology and tools, fracture detection and so on. Based on investigating the fracturing theoryof horizontal well and its process research status at home and abroad.Taking geological characteristics of Sulige gas reservoir in to consideration,the articalanalyzed the influence to production of geological parameters and construction parameters ofvarious size respectively.The fracture and construction parameters were optimized aswell,formed a block guidance on the overall scheme.Simulation research was conducted on theproduction performance prediction and fracture morphology. An optimization design ofhorizontal well fracturing scheme was carried out and got some guidance of field horizontalwell fracturing and design principles,which may better guide the optimization design and siteconstruction of horizontal well fracturing.
