Study Of The Physical Parameters Of Different Types Of Sand Body Reserves

Petroleum and gas reserves,which are compositive reflection of oil and gas expioration , are storage of oil and gas underground. So it is very important to calculate the reserves accurately. We choose proper method for different pools because we should offer accurate reserves calculation. Using the data from logging in a net of high density, the sand core from a airtight well, and the testing data for oil and gas , and then according to the experiment of exploitation, we studied the deposit visage in macroscopical way, the physical characteristics of the reservoir, and the partition of the oil and gas's border. It is clear that the zero group of Sa's oil floor is mainly deposit in the foreside of a delta under the background of lake incursion, and the ventro-delta express a character that there were some sandstones which was transited for two times. Make a certain that the oil and gas's border of zero group in Sa, and tell us that it lies in the top of the anticline. Of course, this production can be used in the designing of the zero group of Sa's exploitation There are many kinds of reserves' calculation. Volume method is one method which will use static state data. We calculate single well's or wells' reserves on the base of different sand body after sedimentation units are subdivided. We get some progression:: 1. calculate single well's area with triangle nets 2. calculate single well's or wells' reserves with static state data, we can get the reserves of different kinds sand body 3. we can use this method get single well's reserves, and could see the distribution of single well's reserves 4. this method which is used to calculate the area of wells may replace the old methods...
