Su Li Ge East Area Compression Fracture Craft Optimization Research

According to the demand of "Su Li Ge east area compression fracture craft optimization research", after generalized anglicizing the material about the Su Li Ge east area reserves geology and preliminary compression fracture construction, I analysis the primary factors that affect east Su Li Ge area compression fracture. Through optimizing this sub-area the compression fractures processing technology to enhance the compression fracture transformation and the individual well production. The main content of my research including:1) In view of the characteristic of Su Li Ge east area gas reserve, according to investigate and study the similar technology of compression fracture processing, especially the multi-thin layer compression fracture and controls seam high compression fracture processing technology, suggest how to change the technology of Su Li Ge east area compression fracture craft.2) Su Li Ge east area compression fracture craft research.①In view of the low injury during the process of compression fracture in Su Li Ge east area, Studies the theory about low-porosity and hypotonic the reservoir fracture injury, especially analysis the theory that the fracturing liquid filtrate clause clay expand. Research the technical measure how to reduce the second injures during the compression fracture process.②Research and analysis biology enzyme broken rubber, the acidic fracturing fluid fracture, the large-scale compression fracture processing technology and condition. Unifies the application situation, appraises whether it is suitable in the east Su Li Ge area gas reserve.③Studies the multi-thin layer compression fracture processing technology, focusing on anglicizing the controlling seam high compression fracture processing technology, and propose what is the suitable technology for this sub-area compression fracture compression fracture processing.3) Study and evaluate the fracturing effect to the east Su Li Ge area.Analysis and evaluate the affection of the biological enzyme, cracked, large-scale fracturing hydraulic pressure to fracturing. ①In view of geological features of the east Su Li Ge area and the reservoir conditions, statistics and analysis the typical wells on each reservoirs in this block in2007, analysis the reservoir’s fracturing with the effect of the relevance of the parameter.②Using the fracturing design software, simulated the materials about the typical wells on each reservoirs in2007. Get the determination of fracture pattern in hydraulic fracturing by geologic engineering method, and analysis the effect of fracture and the parameter of the relevance of construction.③With the reservoir, and technical information of the reform process to fracturing, Analysis the main factors which effect on fracturing in the east Su Li Ge area.4) The research about the parameter of fracture in the east Su Li Ge area.①The study about how to optimize the design in fracturing different permeability reservoirs.②Basing on the simulated production of the fractured gas wells, studied how to design the way of fracturing the main reservoirs, optimized the design of the scale of fracturing the main reservoirs.③Basing on the geological features of the reservoirs, designed the intensity of fracture, the program of pumping, Construction displacement.④Considering the different characteristics of the reservoirs, suggests the typical program of the pumping, Summaries the assessment of study the fracture, and gives some proposals about fracture of the district in the future.5)According to summarize the results of fracture evaluation, we propose the understanding and suggestion of future fracture reform about this section.
