Description
Technical field
The present invention relates to oil, geology, mining industry exploratory development technical field, particularly one carries out mud shale mensuration in laboratory, is a kind of method measuring total porosity of shale.
Background technology
To in the exploratory development process of shale oil gas, total porosity calculates one of oil shale fuel, shale gas stock number and the key parameter formulating recovery scheme.The total porosity of oil shale fuel and shale gas reservoir directly affects the stock number of oil shale fuel, shale gas, and for evaluating the production cycle of oil shale fuel, shale gas well.The source bed of oil shale fuel and shale gas and reservoir are same set of mud shale, and in mud shale, sizable a part of hole is disconnected mutually, i.e. " stagnant pore ".In this part mutual disconnected hole, the attached oil gas deposited can for exploitation through fracturing reform, therefore need to measure the total porosity of oil shale fuel gas reservoir, so that calculate the stock number of shale oil gas, and the production cycle of oil shale fuel gas well assess.At present, the basic skills measuring blowhole comprises: gas method, liquid processes.Gas method is that rock sample is put into obturator, is filled with gases at high pressure, asks for rock porosity according to Boyle law in device; Liquid processes rock sample is vacuumized saturated kerosene (or saturated alcohol), utilizes the weight difference before and after the saturated kerosene of rock sample to ask for factor of porosity.But these methods all can only measure the hole be interconnected in rock, and cannot measure the size of mutual nonconductive pore, namely can only measure net porosity, cannot total porosity be measured.Therefore, by the basic skills measuring blowhole, evaluation is carried out to oil shale fuel gas reservoir and porosity value can be made less than normal, truly can not reflect the total porosity of shale reservoir, and then affect the production cycle assessment of shale oil gas Resources calculation and oil shale fuel gas well.
Those skilled in the art commonly use the apparent volume that immersion method measures mud shale sample.Its volume can be measured with immersion method for the water insoluble sample in irregular shape also do not absorbed water.All be submerged in water by testing sample, the volume differences of twice reading is the apparent volume of sample.Mud shale sample for water suction can replace hydromining immersion method to measure its apparent volume with fine powder (as flour sand, flour etc.).
Pass through patent retrieval, Chinese patent, there is larger defect in 201110155601 applications for a patent for invention of having announced " method for measuring porosity of mud shale " (application publication number: CN 102252948A): think that mud shale is identical with the density after pulverizing before pulverizing, with the sample quality M after pulverizing in principle
1with density p before pulverizing
bratio ask for the volume before pulverizing.(be crushed to granularity and be less than the minimum non-interconnected hole of sample in mud shale crushing process, be equivalent to the grain size of Nano grade) large calorimetric can be produced, make water in mud shale, wet goods fluid becomes gaseous state and discharge from pulverizing sample because of heating, before pulverizing like this and the density pulverizing rear mud shale sample changes.There is deviation in mud shale factor of porosity calculated like this.For this reason, the present invention adopts locking device to utilize circulation fluid (can play the effect of cooling, circulation) to carry out circulation to mud shale sample and pulverizes, and asks for mud shale factor of porosity have higher precision by the volume change before pulverizing and after pulverizing.
